用ViewFlipper实现滑屏，带有层叠转屏效果
package com.android.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
import android.view.GestureDetector.OnGestureListener;
import android.view.View.OnTouchListener;
import android.view.animation.AnimationUtils;
import android.widget.ViewFlipper;

public class CascadeViewFlipper extends ViewFlipper implements OnTouchListener, OnGestureListener{
private final Context context;
private GestureDetector gestureDetector;
protected int FLING_MIN_DISTANCE = 100;//横向滑动多少后才能转屏
GestureDetector mGestureDetector;//监听事件
int currentIndex = 0;//初始化在第一个位置

public CascadeViewFlipper(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
gestureDetector = new GestureDetector(this);
setOnTouchListener(this);//对viewflipper设定监听事件,很多人都忘记写要注意
setLongClickable(true);
}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
/**
* 向左滑动
*/
if (e1.getX() - e2.getX() > FLING_MIN_DISTANCE) {
if (currentIndex < getChildCount() - 1){
currentIndex++;
setInAnimation(AnimationUtils.loadAnimation(context, R.anim.cascade_left_in));//设置向左滑动进来页面的动画效果
setOutAnimation(AnimationUtils.loadAnimation(context, R.anim.cascade_left_out));//设置向左滑动页面出去的动画效果
showNext();
}
return true;
}
/**
* 向右滑动
*/
else if (e1.getX() - e2.getX() < -FLING_MIN_DISTANCE) {
if (currentIndex > 0){
currentIndex--;
setInAnimation(AnimationUtils.loadAnimation(context, R.anim.cascade_right_in)); //设置向右滑动进来页面的动画效果
setOutAnimation(AnimationUtils.loadAnimation(context, R.anim.cascade_right_out)); //设置向右滑动页面出去的动画效果
showPrevious();
}
return true;
}
return false;
}

@Override
public boolean onTouch(View v, MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}

@Override
public boolean onDown(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}

@Override
public void onLongPress(MotionEvent e) {
// TODO Auto-generated method stub

}

@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
float distanceY) {
// TODO Auto-generated method stub
return false;
}

@Override
public void onShowPress(MotionEvent e) {
// TODO Auto-generated method stub

}

@Override
public boolean onSingleTapUp(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
}

Activity的代码：
package com.android.view;

import android.app.Activity;
import android.os.Bundle;

public class Main extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view_flipper);
}
}
